Quick answer

Fit the Halti headcollar snugly behind the ears and around the muzzle, then attach the leash to the ring under the chin. Use gentle guidance rather than yanking to teach loose-leash walking.

Why a headcollar works for pulling dogs

A Halti headcollar works by gently steering your dog's head, which naturally controls the direction of their body. Unlike a collar that puts pressure on the throat, the headcollar's design distributes pressure across the nose and poll. This makes it a humane alternative for dogs that pull on leash, especially during training sessions. The reflective webbing on COA Halti models also adds visibility during low-light walks.

Sizing and fit considerations

Getting the right size is critical. A headcollar that is too loose can slip off, while one that is too tight can cause rubbing or discomfort. COA Halti headcollars come in multiple sizes—Size 1 for small breeds, Size 3 for medium, and Size 5 for large dogs. Measure your dog's muzzle circumference and neck girth, then compare to the brand's size chart. If between sizes, choose the larger one and adjust the straps for a snug but not tight fit.

Step-by-step: How to fit and use a Halti headcollar

  1. Step 1: Introduce the headcollar slowly: Let your dog sniff the headcollar first. Offer treats while holding it near their nose. Do not try to put it on right away—build positive association over several sessions. Common mistake: rushing the introduction can make the dog fearful of the headcollar.
  2. Step 2: Fit the neck loop: Loosen the neck strap fully. Place the loop over your dog's head so it sits high on the neck, just behind the ears. The buckle should be on the side or back. Tighten until you can fit two fingers between the strap and your dog's neck. Checkpoint: if the neck loop slides forward toward the eyes, it is too loose.
  3. Step 3: Position the nose loop: Gently guide the nose loop over your dog's muzzle. The loop should sit about halfway between the eyes and the tip of the nose. The strap that connects the nose loop to the neck loop should lie flat on the bridge of the nose. Common mistake: placing the nose loop too far forward can cause rubbing on the nostrils.
  4. Step 4: Adjust for a snug fit: Tighten the nose loop so it is snug but not tight—you should be able to slide one finger under the strap. The headcollar should not twist or slide off when your dog shakes their head. Re-check both straps after the first few minutes of wear. Checkpoint: if the headcollar rotates around the muzzle, the nose loop is too loose.
  5. Step 5: Attach the leash and start walking: Clip the leash to the ring under the chin (not the top ring, which is for the safety strap). Hold the leash loosely and let your dog move. When they pull, gently guide their head back toward you using steady, light pressure. Reward any slack in the leash. Common mistake: jerking the leash can cause neck strain—always use gentle, steady guidance.
  6. Step 6: Use the safety strap (optional but recommended): If your dog is a strong puller or prone to backing out, attach the included safety strap from the headcollar to your dog's regular collar. This prevents the headcollar from coming off completely if it loosens. Checkpoint: the safety strap should be short enough that the headcollar cannot slip past the muzzle.
